SIDE GUIDE FOR PAPER-FOLDING MACHINES.

SPECIFICATION forming part of Letters Patent No. 438,804, dated October21, 1890.

Application filed May 14, 1889.

To all whom it may concern.-

Be it known that I, HUBERT GARDINER, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Side Guides forPaper-Folding Machines, of which the following is a full, clear, andexact description, reference being had to the accompanying drawing,which is a perspective view of the invention as applied to thewell-known Chambers newspaper-folding machine, only so much of thelatter being shown as is necessary to illustrate the invention.

The nature of this invention is a paperguide for folding and analogousmachines, said guide being adapted to determine the proper position inwhich to place the side edge of a sheet of paper that is to be seized bythe drop-rollers or grip mechanism of such machines, then toautomatically recede so as to allow the sheet to be drawn in obliquely,if desired, or to allow the sheet, if wider at its back than at itsforward end, to pass the guide 25 without the edge of the sheet ineither case being drawn or scraped against said guide.

The invention consists, primarily, in the combination, with thefeed-table and the grip mechanism of a machine of the character stated,of a movable guide-bar adapted to be operated in concert with saidmechanism, substantially in the manner and for the purpose hereinafterfully described.

The invention consists, also, in certain features of construction,details, and combinations, which will be duly explained and definitelyclaimed.

Referring to the drawing, A represents a section of the feed-board of apaper-working machinesuch, for example, as the wellknown Chambersnewspaper-folder.

B is the carrying roller or drum.

' O is the drop-roller mounted in the frame O, and E is one of thesheet-carrying tapes.

In the top of the boardA near its delivery end is cut a transversegroove a, in which snugly fits flush with the board a double grooved orchanneled metal plate F. This plate is stationary, and has mounted andadapted to slide thereon a bracket G, whose Serial No.3l0,775. (Nomodel.)

base g is provided with ribs 9 that register with said grooves. The baseis also provided with a central longitudinal slot g through which passesa bolt g that enters the plate F and thus secures the bracket in place.By properly turning this bolt the bracket may be adjusted sidewise andfixed at the point of adjustment. A series of bolt-holes f is formed inthe plate F, so that the range of adjustment of said bracket may beincreased as desired.

In the top of the upright g of bracket G is journaled a rock-shaft H, towhose near end is secured a guide-bar I. The lower end of the latter isbifurcated, as seen, and its limbs extend into the grooves f in thefixed plate F. On the other end of this shaft His a fixed horizontal armh, whose free end is connected by means of a rod 71, with a transversebar .I in the drop-roller frame 0. The lower end of this rod is providedwith a sleeve 7L3, which slides freely on the bar J, and said rod passesthrough a notched boss 9 on the end of the guide-bar g that extends fromthe bracket G.

From the foregoing-described construction it will be seen that when thebracket G is moved for adjustment, as above mentioned, all the partsmounted thereon will go with it without changing their positionsrelative to each other and to the drop-roller frame. Hence the device asa whole may be moved sidewise, as circumstances may require, withoutnecessitating any rearrangement or re adjustment of the parts.

Following is the operation: Asthe droproller is raised in the usualmanner, the machine being ready to receive a sheet for folding or otherpurposes, the rockshaft arm h, which is connected with the roller-frame,is likewise raised by the latter, thus turning the shaft H and throwingforward the side guide I thereon, as indicated by the dotted lines. Whenin this outward position, the edge of the sheet is placed against theguide, or near thereto, the position of the end of the sheet beingdetermined in the usual manner by the well-known sight or other gages.(Not shown.) When the drop-roller and its frame descend, the guide I isreturned by the intermediate mechanism described to its first or backpo- 10o sition, as shown, the sheet being seized between the drop-rollerC and carrying-roller B and drawn into the machine in the direction inwhich it may have been started. Thus if the sheet be started slightlyoblique, or if its back end be wider than its forward end, the sides ofthe sheet will not rub or scrape against the guide, as would be the caseif the latter were stationary. It will be evident that this guide devicemay also be advantageously used in connection with those wellknownmachines wherein the sheet is started obliquely in order to permit itsbeing carried over sidewise to a certain position, so as to secure sideregister, whereupon the paper strikes a long side guide, against whichit squares itself before being operated upon by the machine.

I here remark that I do not restrict myself to the specific constructionand arrangement of parts herein shown and described, as the same may bevariously modified by one skilled in the art to which my inventionappertains without departing from the essential principle thereof.

Having thus described my invention, I claim as new and wish to secure byLetters Patent- 1. In combination with the feed-board and the grippersof paper-folding or analogous mechanism, a reciprocating side guide-baroperated in concert with said grippers, being moved inward when thegrippers are open or inactive, so as thereupon to act as a determinateside gage, and being retracted when such mechanism is closed or active,whereby an obliquely-fed or oblique-sided paper sheet whose positionwith lateral relation to said grippers has been determined by theguidebar will pass to the folding or analogous mechanism withoutimpinging against said bar, substantially as described.

2. In a paper-folding or analogous machine, the combination, with thefeed-board and the grip mechanism, of a movable side guide arranged withrelation to said board and grip mechanism, substantially as described,and connected with and operated by said mechanism, substantially as andfor the purpose set forth.

3. In a paper-foldin g or analogous machine,

the combination, with the feed-board and the grip mechanism, of thesupporting-bracket, the rock-shaft, and the side guide-arms thereon,said shaft being connected with and operated by said grip mechanism,substantially as and for the purpose set forth.

4:. The combination, with the feed-board and drop-roller frame of apaper-folding or analagous machine, of the supporting-bracket, therock-shaft journaled therein, its arm 71., the rod connecting said armwith said frame, and the side guide-bar connected with said rock-shaft,substantially as described.

5. In a paper-folding or analogous machine, the combination, with thefeed-board and the drop-rollerframe,of thebase-plate,thebracketadjustably secured thereto, substantially as described, the rock-shaftjournaled in said bracket, the arm 72., and the rod connecting saidframe and arm and movable laterally 011 said frame, together with theguide-arm connected with said rock-shaft, substantially as and for thepurpose set forth.

6. In a paper-folding machine, &c., the eo1nbination, with thefeed-board and the droproller frame, of the base-plate, the slottedbracket provided with the notched or recessed arm g", the conneating-bolt, the rock-shaft, its arm h, the guide-bar, and theconnectingrod 7L2, provided with the sleeve at its lower end, togetherwith the transverse bar J, all substantially as described.

'7. The combination,in a paper-folding machine, &c., with the feed-boardand the droproller frame, of the grooved or channeled base-plate, theribbed and slotted bracket provided with the notched or recessed arm 9the connecting bolt or screw, the rock-shaft, its arm h, the bifurcatedguide-arm engaging with said base-plate, and the connecting-rod providedwith the sleeve at its lower end, together with the transverse bar J,all substantially as and for the purpose described.

In testimony whereof I have hereunto aflixed my signature this 19th dayof March,

HUBERT GARDINER. IVitnesses:
